Collections pages not loading until page refresh

Our store is experiencing an intermittent issue where collection pages won’t load until the page is refreshed. After speaking with Shopify Support, they confirmed this is a known issue affecting multiple stores. Their current solution is reindexing, but we’re looking to understand if this is happening to others and if anyone has found a long-term solution.

Has anyone else dealt with this recently? If so, has reindexing provided a lasting fix for your store? Any insights would be greatly appreciated.
